通过分析列车在限速区段的运行特征，提出了四显示固定闭塞系统下限速区段列车流的元胞自动机模型，重点研究了混合列车流在限速区段的运行特性以及列车在限速区段的延误规律，并分析了造成列车延误的原因。结果表明：当客货车在具有限速区段的线路混行时，造成列车延误的原因分为限速区段限速和货车对客车的抑制作用，且列车延误时间随着限速区段长度的增加而增加；货车对客车的抑制作用随着发车间隔的增大而减弱，当发车间隔超过临界值时，造成列车延误的主要原因是限速区段的限速。当发车间隔固定时，列车的平均延误时间会随着客货车比例的增大呈现出“拱形”，客货车比例在0.55~0.65之间时，列车的平均延误达到了峰值。

By analyzing the operational characteristics of trains in speed-limited section, it proposes a cellular automaton model for train movements in the four-aspect fixed-block system. The operational properties and delay laws of traffic flow of mixed trains are investigated in this paper, and the reasons causing operational delay are also analyzed. The results show that when the passenger and freight trains operate on the same railway, the reasons which cause the delay are speed-limit and inhibiting effect of freight trains to passenger trains, and the delay time increases with the length grow of speed-limited section. The inhibiting effect decreases with the increasing of train departure interval, and once it is greater than a critical value, the main reason inducing train delay is only speed-limit of slowdown section. When the train depar-ture interval maintains a constant value, the average delay time of trains will form a“arch”with the increasing proportion of passenger and freight trains, and when the proportion ranges from 0.55~0.65, the average delay time reaches to maximum.
